Rose: The Softest Armor Ever Grown

The word arrived long before the flower we know. Latin rosa comes from Greek rhódon, and rhódon comes from an old Iranian root, wrd-, that survives in Avestan varəda and Armenian vard. The chain is still visible in words nobody reads as floral any more: a rhododendron is a "rose tree", and the island of Rhodes struck coins with a rose on them for centuries.

In modern Persian the rose is gul — and gul slowly came to mean "flower", full stop. The rose ate the generic word. It is the only flower we know of that managed that.

The Romans gave it a second job. Banquet rooms were decorated with carved or painted roses, following the myth in which the rose was Venus's gift to her son, who passed it on to Harpocrates, the god of silence. A rose on the ceiling meant that whatever was said under it stayed there: sub rosa, under the rose. Christianity inherited the habit and carved roses onto confessionals, where the same promise applied.

And there is a family surprise. Rosaceae includes the apple, the pear, the cherry, the plum, the strawberry, the raspberry, the blackberry — and the almond. When you eat an apple you are eating a cousin of the rose. Two of the trees we have already written about are Rosaceae too: the almond tree and the Kanzan cherry. The rose keeps better company than its reputation suggests.

The rose is a wild plant that became a logistics operation. Three countries move most of the world's stems: the Netherlands, Ecuador and Kenya, with the United States as the largest buyer. The Dutch position is the odd one — the country is simultaneously the biggest exporter and one of the biggest importers, because it buys equatorial flowers grown where the light never varies, then grades, bunches and re-exports them through its own auction system. It is the same infrastructure, and the same instinct, that built the tulip trade four centuries ago.

Our studio is in Barcelona, and here the rose has a date. Every 23 April, for Sant Jordi, Catalonia sells around seven million roses in twenty-four hours. In the last edition, 63% came from Colombia, 20% from the Netherlands, 15% from Ecuador and barely 2% from local growers; the dominant colour was red, and the varieties were 'Freedom' and 'Naomi'. The abstract trade table becomes very concrete when it is the flower someone hands you in the street.

Around 150 wild species, and somewhere between thirty and thirty-five thousand cultivars on top of them. Any selection is arbitrary, so here are the ones that say something: the rose that industry runs on, the rose that broke the rules of what a rose looks like, and the rose that had to be engineered because it could not be grown.

Rose otto is one of the most expensive materials in perfumery, and the reason is arithmetic rather than mystique: roughly 4.5 tonnes of petals yield a single ounce of oil, and the petals have to be hand-picked at dawn, because the volatiles leave as the sun rises. The two great species split the market — Rosa damascena, distilled in Bulgaria, Turkey and Iran, and Rosa centifolia, the May rose of Grasse, which flowers once a year.

Inside that oil there is a figure worth stopping on. The scent is built on citronellol, geraniol, nerol and phenylethanol, but the compound that decides its character is β-damascenone, which accounts for about 0.1% of the oil and roughly 70% of what we actually smell. Its detection threshold is among the lowest ever measured.

Which makes the supermarket rose easier to forgive. For decades, cut-flower breeding selected vase life, stem length, colour and resistance to transport. Perfume is metabolically expensive for the plant and evaporates in transit, so it fell outside the criteria. The best-selling rose in the world is often the one that smells of nothing — not by accident, but by specification.

And then there is the fruit, which most people never associate with the flower. The hip of Rosa canina carries around 400 mg of vitamin C per 100 g, against roughly 50 in an orange. When citrus imports were cut off in the Second World War, Britain organised a national rosehip harvest from 1941 — schoolchildren included — and turned hedgerows into syrup.

No other flower has been asked to mean so many incompatible things at once. In classical antiquity the rose belonged to Aphrodite: desire, beauty, and the short life of both. In the same culture, on the same ceiling, it meant silence. Christianity then took the whole apparatus and reassigned it — the white rose became the purity of the Virgin, and the string of prayers named after garlands of roses became the Rosary.

Politics used it as a uniform. In the fifteenth-century English dynastic wars, the white rose stood for York and the red rose for Lancaster, and the conflict took the flower's name. Two colours of the same species, on two sides of the same war.

The mystics went further in. Sufism calls the pursuit of divine truth the Path of the Rose. The Zohar uses a thirteen-petalled rose for the thirteen attributes of Divine Mercy. Rosicrucianism binds the geometric cross to the unfolding flower. In every case the reading depends on the same physical fact: a rose is a structure that opens, layer after layer, and never shows you everything at once. Like the poppy, it is a flower we read partly because it does not last.

Ten works, in chronological order, from an illuminated manuscript to an abstraction. The line stops in 1920, and it stops there for legal reasons rather than aesthetic ones: everything past that date is still in copyright and we cannot reproduce it here. The rose's visual history obviously does not end with Klee — Georgia O'Keeffe put it on monumental canvases, Robert Mapplethorpe photographed it in high-contrast black and white, Andy Warhol turned it into a repeatable product. We can name them. We just cannot show them.

Look at the last two. Klimt's Rosebushes under the Trees is a field of marks from edge to edge in which the roses very nearly disappear — the flower dissolved into texture. Klee reduces them to spirals on a surface with visible body and impasto. Six of the ten are from 1883 onwards, and the sequence ends in abstraction, which is where our own work lives: not the rose described, but the rose as a surface that holds light.

Four people who changed what the rose means: the patron who financed its modern form, the painter who fixed its image, the poet who wrote his own epitaph about it, and the writer who tried to give the word back its weight. Before all of them, Cleopatra — who, legend says, filled a room with rose petals a foot deep, the earliest recorded case of a flower used as an instrument of persuasion.
